I have illustrated and described my invention in an embodiment which Ihave found highly satisfactory. I have not attempted to illustrate ordescribe certain modifications or adaptations which I contemplate as itis believed that this disclosure will enable those skilled in the art toembody or adapt my improvements as may be des red.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is:

1. In a spray head, the combination of a tubular body member provided atthe top thereof with an annular recess having an inwardly inclinedbottom andwith an internal annular shoulder and having a longitudinalinternal groove above said shoulder, an internally shouldered tubularnozzle member provided with an upwardly flared tip portion adapted toseat in said recess in said body member and having an annular upstandingperipheral flange, the edge of which is flush with the top of the bodymember when the nozzle is retracted, an inverted conical baiile memberprovided with a stem and adapted to seat within said nozzle tip andconstituting a closure therefor when seated, a passage member disposedwithin said nozzle member against said shoulder therein and having aplurality of spirally disposed peripheral grooves coacting with thewalls of the nozzle member to provide spiral passages, said passagemember having a central conical opening receiving said stem, said stembeing provided with a conical head seating in said opening when thebaffle member is in elevated position, a tubular stem for said nozzleprovided with a flange at its lower end coacting with said shoulder insaid body member, and a coupling threaded into said nozzle member andinto which said nozzle member stem is threaded, .said coupling beingprovided with a lug engaging said longitudinal groove in said bodymember.

2. In a spray head, the combination of a tubular body member provided atthe top thereof with an annular recess having an inwardly inclinedbottom and with an internal annular shoulder and having a longitudinalinternal groove above said shoulder, a tubular nozzle member providedwith an upwardly flared tip portion adapted to seat in said recess insaid body member and having an annular upstanding peripheral flange, theedge of which is flush with the top of the body member when the nozzleis retracted, an inverted conical baiiie member provided with a stem andadapted to seat within said nozzle tip and constituting a closuretherefor when seated,

tubular body member provided with a recess at the top having an inwardlyinclined bottom, said body member having a longitudinal internal groove,of a tubular nozzle member provided with an upwardly flared tip portionadapted to seat in said recess in said body member, said nozzle memberhaving an internal flange at the base of its conical tip portionproviding a restricted throat and an internal shoulder substantiallyspaced from said flange, a passage member disposed within said nozzlemember against said shoulder therein, said passage member havmg acentral conical opening, an inverted conical baffle member provided witha stem, said stem having a conical head fitting said conical opening insaid passage member when the baflle member is in its projected positionwhereby the baflle member is centrally supported with said stemcentrally of said restricted throat when the baffle member is inprojected position, and a coupling threaded into the inner end of saidnozzle member and provided with a lug engaging said groove in said bodymember.
